A senior advisor for Pauline Hanson has been involved in a fight with a former One Nation senator.
James Ashby and Brian Burston have been caught on camera pushing and shoving in Parliament House.
The altercation came as Ms Hanson appeared on Sky News to deny claims she had sexually harassed Senator Burston.
Mr Burston, the only elected member of Clive Palmer's United Australia Party, alleges he faced unwanted advances from Ms Hanson over a period of two decades.
Ms Hanson has laughed off the allegations, saying ‘I might be 64 but I’m not desperate.’
